Enum TextDirection 

pub enum TextDirection {
    Ltr,
    Rtl,
}

Base writing direction for a shaping request.

Controls the rustybuzz buffer direction so glyph advances and complex-script joining (e.g. Arabic) are correct. The DEFAULT is TextDirection::Ltr, so a request that omits the field shapes exactly as before (byte-identical).

Variants

Ltr

Left-to-right (the default).

Rtl

Right-to-left (Arabic, Hebrew, …). The shaper reorders glyphs to visual order and applies RTL-correct joining.

Trait Implementations

impl Clone for TextDirection

fn clone(&self) -> TextDirection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TextDirection

impl Debug for TextDirection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TextDirection

fn default() -> TextDirection

Returns the “default value” for a type.

impl Eq for TextDirection

impl PartialEq for TextDirection

fn eq(&self, other: &TextDirection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
